HARMFUL BLUE RAY
The first danger of blue light is to damage the tissue structure of the eye. Harmful blue light has extremely high energy and can penetrate the lens directly to the retina, causing atrophy and even death of retinal pigment epithelial cells. Blue light can also cause macular degeneration. The lens in the human eye will absorb part of the blue light and gradually become cloudy to form cataracts. The lens is relatively clear and cannot effectively resist blue light, which may lead to macular disease and cataracts.
The second hazard of blue light is that it can easily cause visual fatigue. Prolonged visual fatigue can cause myopia to deepen and diplopia. The inability to concentrate while reading affects people's learning and work efficiency.
The third hazard of blue light is affecting sleep. Blue light can inhibit the secretion of melatonin, which is an important hormone that affects sleep.
